Specification ofLetters Iatent.

' Patented March 13, 1906.

Application filed July 31, 1905. Serial No. 272,085-

1'0 au whom it may concern.-

Be it 'known' thatI, AAUGUST BRAUNS, a America, and countyof Brown,State of Wisconsin, have invented certain new and useful lImprovementsin Rubber tated freely Erasers, o f which the followinr a full andclear'speclfcatlon, reference being had to the accompanying.drawings7 inwhich i F1gure 1 represents a side lelevationof ay leffd-Pellil providedwith my improvement; F1g. 2, a similar view showing the rubber tip inthe act of 'being screwed into its holdingcylinder, and` l `.ig.v 3 alongitudinal section with the parts secured'togethe'r as in Fig. 1.

The object of this-invention is to so mount and attach the rubber tipthat it-maybe rowhile in use, thereby avoiding may be on the paper, as.more full hereinafter setforth. To the-accomplis meotof this object andsuch others as may herein-v after appear, the invention consists of theipalrts and combination of arts hereinafter l descr1bed,`and particuarly pointed out .-in t e appended claims, .reference being had to theaccompan drawings, forming a part of this'spec cation, in which the samereference characters designate' like parts f3 i throughout theseveral'views.

Fastened rigidly on the end of the encil is a sleeve-.like cap a, Awhichis preferab y fitted on a reduced extension bof the pencil.

This cap is enlargedat its closed end to form a head c, .and near theother end of the sleeve' is formed an annular-rib or projection d ofless height than the lshoulder formed by the head c.

`The rubber eraser-tip' e is screwed into a sleeve f, which is rotatablmounted upon the permanent sleeve a. T is'sleevefis rovided at g with anannular shoulder, W ich v abut's against the shoulder formed by the Yhead c and prevents the sleeve slipping E over said head c. The rubbertip e is screwed intothe open endof sleeve f far enough to come lightlyin contact with the head ofk l* o. I x struction permits the sleeve f,carryingV the l-'sleeve, and the annular shoulder sleeve fa, therebykeepingl the annular` shoulder g in loose contact Wit the annularshoulder on the permanent sleeve/ This conrubber, to rotate freelyon'the ermanent bearing' for the lower or inner end of therotatableseeve, keeping it out of frictional-'conaffords a,-

e the parts isshown'in Fig. 2. The rotatable sleeve is first `slipped onover the point end of the pencil until its shoulder g comes into contactwith the shoulder of the'head c. Then the parts are secured in positionby screwing in the rubber ti pIn using the device the operator graspsthe pencil in such a manner as, to leave the rotatable sleeve free torotate; and then by properly adjusting the angle of the pencil ywithrespect to the paper W 'ile rubbing t-he eraservtip will rotate 'and atthe same time cause enough friction on the paper to remove the dirt orpencil-marks, or the operator may grasp fthe body of ythe pencil in suchmanner as to leave the thumb and foreiinger free to grasp and turn thetip-carrying sleeve during the act-of using the device without turnf ingthe body of the pencil in his hand. Thus permittingpr causing the rubberpart to rotate during theI act: of` erasing constantly brings newrubbing-surfaces into contact wit the pa er' and carries away dirt andgraphite that t e rubbing action collects, thereby avoiding streakingand smearing the pa er. Having thus described my invention, w at Iclaim, and desire tosecure by Letters Pati 1. In Acombination with alead-pencil, a non-rotatable cap or sleeve fitted on over the endthereof, this sleeve being `provided with an annular head at its outerend and an annular ila ve or projection at its inner end this lattereing of less height than the `head portion, a rotatable sleeve enlargedat its outerv end to forma socket for the head or-` tion of theypermanent Sleeve, and a ru ber tip removably fastened inthe outer endofy said rotatable sleeve, for' the purpose set forth.' l c 2. Incombination with a pencil, a freelyrotatable sleeve mounted thereon-andproj ectingtbeyond the end of the pencil and carrying a 'rubber eraserin said projecting portion, said rubber eraser being fastened to thesleeve so as to rotate with it, substantially as 3. In combination witha4 vlead-pencil, a non-rotatable cap or sleeve ttedon over the endthereof, this sleeve `being provided With TIO an annular head at itsouter end, a rotatable signature, in the resenoe of two witnesses,sleege Fnlalgega its outerfelllld to forma this 29th day of Ju y, 1905.l soo et or t e ea ortion o t e ermanent sleeve, and a rubheg ti removaby fastened AUGUST BRAUNS 5 in the outer end 'of sai rotatable sleeve,for Witnesses: the purpose s et forth.
